Yucca Moth - Tegeticula sp.
I present to you all a new delightful new specie for the blog, and a rare specimen at that. We'll need to make a small detour back to the order Coleoptera for a bit of content since there is another insect that favors the plant alongside this fluffy Moth (even though I mentioned previously that Coleoptera had been examined enough for now). With summer getting warmer and rain nourishing the plants of the neighborhood, yucca plants create their long stalks and unveil their flowers with hopes of pollination. The ones in our yard have yet to open, but when they do, I'm expecting the Brown Yucca Beetles to return and make the most of the flowers for themselves and devour the nourishment they have to offer. While those little beans are common, the more interesting insect to document while watching yuccas blossom are the Yucca Moths of the family Prodoxidae. For the purposes of identification, Yucca Moths all have a similar form, but are not limited to white plumage. Some have dark spots, and their hindwings can feature dark colors and some even appear golden. Pay close attention to the colors of their legs and antennae as well. Looking beyond appearances, these creatures are the sole effective pollinators of yucca flowers and the yucca plants themselves are a food source for the hungry Moth larvae.
The interactions between this insect and plant has resulted in a special mutualistic relationship over the years. Specifically, it's to the point where they've influenced each other's evolution and they need each other in order to exist. In instances of True Yucca Moths, the adult Moth pollinates the flower and ensures seed production as a result; the Caterpillars later on feed on the developing seeds (and the stem innards) of the plant. There's always enough to go around, and yet Yucca Moths are quite rare in Ontario. There are instances however, where other Yucca Moths don't pollinate the plant but still lay their eggs somewhere on the plant (they've earned the name Bogus Yucca Moths - genus Prodoxus) to ensure their Caterpillars will have food when they hatch. This individual is definitely a pollinator though as can be discerned from Picture 5. Bogus Moths feed on plant using a coiled proboscis while pollinating Moths have grasping mouthparts which they use to roll pollen into puffs and carry them to other yucca flowers. It's by pure luck that I noticed this one, but I'm glad it chose me and landed on my land.
Pictures were taken on June 25, 2023 with a Google Pixel 4. The post uploaded early before the final draft was pasted in, apologies for that.
